Bristoe,
Ah! I was going to suggest the next size up and swage it down. In my case it didn't help much but I didn't work with it. More or less figured the twist was too fast, like ball versus conicals in a muzzle loader. Be careful with Titewad, think Bullseye. Notes say Titewad is extremely position sensitive, in an 8mm x 57 "cat sneeze" round anyway.
